of Fig. 1; of Fig. 1,

Be it known that I, ANTHONY J. PowERs, a citizen of the United States,residing at Meridian, in the county of Lander-dale, State ofMississippi, have invented certain new and useful. ImprovementsinFinishing-Machines; and I do hereby declare the followingto be a full,clear, and exact description of 'theinvention, such as will enableothers skilledin the art to which it appertains to This inventionrelates to finishing machines for use in the construction of con cretepavement and walks.

The object of the invention resides in the provision of a machine of thecharacter named which is adapted to be supported by and travel upon theside members of a concrete walk form and which includes mechanismoperable during movement of the machine for smoothing and finishing theupper surface of the walk.

A further object of the invention resides in the provision of a machineof the character named which can be operated with great rapidity so thata'resultant saving in time and labor will be had.

A still further object of the invention re-' sides in the provision of amachine for finishin the upper surface of concrete walks whic will besimple in construction, eiiident in use, and which may be manufacs.

tured at a comparatively small cost.

With the above and other ob ects in view the invention consists in thedetails of 0011- struction and in the arrangement and combination ofparts to be hereinafter more fully described and particularly pointedout in the appended claims.

In describing the invention in detail reference will be had to theaccompanying drawings wherein like characters of reference denotecorresponding parts in the several views, and in which- Figure 1 is aplan view of a machine constructed in accordance with the invention;

Referring to the drawings 10 and 11 in- 5, a section on the line 5-5"dicate the side members mentform and upon which the machine is adaptedto travel during its operation. These side members 10 and 11 areconstruct- .ed of angle iron and which includes an-outwardly directed 11per flange 12 provided with a longitudina groove 13.

of a concrete pave- The machine is shown as comprising a.

frame A which includes upper side members 14 and 15, and lower sidemembers 16 and 17. The frame A further includes upper end members B andG each ofwhich is formed of sections 18 and 19 which are connectedtogether by a plate 20. -These sections 18 and 19 and the plate 20 areprovided with a plurality of openings 21 certain of which are adapted toregister as the sections 18 and 19 are moved longitudinally of the plateso as to permit the insertion of bolts 22 therethrough to secure thesections and plate together. The frame A also embodies lower end membersD and E,each-l. of"

which comprises sections 23 and 24 secured by a plate 25 in a mannersimilar to the connection between the sections 18 and 19 of the upperend members B and C. By this construction it will be apparent that thewidth of the'frame A may be varied so as to meet requirements andconditions.

The frame A is supported upon a pair of axles journaled in the lowerside members 16 and 17. Each of these axles comprises sections 23 and 24which are slidably mounted in a sleeve 25 wherebythe axles may be variedin length so as to conform to variations in the width of the frame A.Mounted in each sleeve 25' is a plurality of set screws 26 for thepurpose of locking the axle sections 23 and 24 against movement and thusmaintaining the axle a given length. Fixed on the outer ends of each ofthe sections 23 and 24 is a toothed wheel 27 which engage respectivelyin the grooves 13 of the side members 10 and 11 of the form.

Extending laterally and downwardly from r of respective flanges Thesemembers 29 serve to hold the machine against upward movement during theoperation of same as will be apparent. Journaled in suitable brackets onthe upper sides 14 and 15 is an operating shaft which comprises sections31 and 32 slidably mounted in a sleeve 33. A plurality of set screws 34are carried by the sleeve 33 and are adapted to engage the sections 31and 32 so'as to lock theshaftsections against longitudinal movementin'the sleeve 33. By thisconstruction'it will be apparent that theoperating shaft can be lengthened and shortened so as to conform'tovariations in the width of the frame A. J ournaled in the frame A is avertical shaft 35 which has fixed on its upper enda toothed gear 36 andon its lower end a disk 37. The

gear 36 meshes with a beveled gear 38 fixed on the sleeve 33 so thatupon rotation of the operating shaft a corresponding rotation of theshaft 35 willbe produced. The lower side member 16 is provided withopenings 39 and 40, while the lower side member '17 is provided withopenings 41 and 42. Adapted to be interchangeably engaged in theseopenings 39, 40, 41 and 42 are the terminals of av floater Fwhichincludes a body portion 43 constructed preferably of wood and afront facing 44 constructed of steel and secured to the body 43 throughthe medium of screws 45. Rising from theupper side of the bodyversely'of the frame A.-, Byinterchange-. ably inserting the terminalsof the floater F in the openings 39, 40, 41 and 42- it will be 43 of thefloater F is a pin 46 which has fixed oniits upper end a lateral arm 47.The free end of this lateral arm 47 is eccentrically pivoted to theundei side of the disk 37 so that as the shaft 35 is rotated the floaterF will be moved both longitudinally and transapparent that the angulardisposition of'the 4 floater with respect to the longitudinal axis ofthe machine may be changed. Formed on, the inner sideof the lower sidemembers 16 and 17 at the rear of the openings 39 and 41 are verticallyalined eyes 48 and 49 respectivelyand slidablymounted in the eyes 48 and49 are rods 50 which terminate at their lower ends respectively in edgetools 51.

Formed on each rod 50 is a flange'52 and encircling each rod between theflange 52 and the eye 48 isa spring 53 which cons stantly tends to movethe rod 50 and edge tool 51 downwardly. Journaledbetween the sidemembers 16 and 17 at the rear of the I edge tool 51 is a shaft 54 whichhas mounted-on each end thereof a sprocket wheel 55;-
